Mercedes Benz 420SEL AC Compressor Parts

Mercedes Benz 420SEL AC Compressor

The Mercedes Benz 420SEL AC Compressor is the central part of your vehicle's air conditioning system. Its primary function is to keep the refrigerant flowing through the AC. The compressor pressurizes and delivers the refrigerant to the AC condenser. The compressor rotor is coupled to the crankshaft through a pulley. The turbine action of the rotor draws the refrigerant gas into the compressor, where it is compressed to a pressure of around 250 psi at a high temperature. The high-temperature, pressurized refrigerant is conveyed to the system's condenser, where it is cooled down into a high-pressure liquid refrigerant. The refrigerant is then passed through the dryer where any moisture present is removed. The expansion valve removes the pressure in the liquid before passing it to the evaporator. In the evaporator, the liquid refrigerant is turned back into a gaseous form, absorbing the heat in the passenger cabin of your vehicle. The coupling between the compressor rotor shaft and the pulley is regulated through a mechanical clutch that only engages when the AC is turned on. A faulty compressor should be replaced at the earliest to prevent your AC system from sustaining severe damage. Common signs of a defective compressor include a refrigerant leak and clutch failure.
